Objective:
Investigate familial aggregation of sinonasal polyps (NP) and correlate the severity of chronic rhinosinusitis (CRS) with a family history of NP.
Study Design And Setting:
A questionnaire documenting NP, asthma, or aspirin intolerance was completed by 174 CRS patients. Severity of sinus disease was stratified as isolated NP, NP with concomitant asthma, and Samter's triad (polyps, asthma, and aspirin intolerance).
Results:
Compared to controls, CRS patients had a higher incidence of a family history of NP. Additionally, patients stratified with severe CRS had a higher incidence of relatives with NPs.
Conclusions:
Familial aggregation of NP is demonstrated in CRS patients and correlates with disease severity.
Ebm Rating:
